Police told WBZ Radio the school was evacuated and students were taken to an “undisclosed location.” They wanted parents to know that their children are safe.

Investigators said the student, who has not been identified, did not threaten anyone.

The principal described the weapon as an “Airsoft BB gun.” Police said it resembled a 9 mm handgun.

According to WBZ-TV’s Peg Rusconi, the teen showed the gun to other students and he is now being evaulated.

School officials found out about the gun when students started texting each other about it.

A spokesperson for the superintendent’s office told WBZ-TV the situation involved a “suspected intruder” but was under control within a short period of time and students were dismissed between 9:45 and 10:15 a.m.

Parents were notified through email and automated phone calls.
